seedance-ai-avatar

A complete system for crafting Seedance 2.0 prompts on Higgsfield that feature AI avatars, digital personas, virtual presenters, and synthetic characters as the primary subject. This skill covers everything from photorealistic digital humans to stylized 3D characters, including hook patterns, environment design, camera work, lighting, and audio direction. ---

Before generating prompts, gather the following from the user: Character definition • Avatar style: photorealistic human / stylized 3D / 2D animated / abstract-geometric • Gender presentation, approximate age, and visual identity descriptors (if applicable) • Skin tone, hair, wardrobe notes, or reference aesthetics • Personality register: corporate, playful, authoritative, futuristic, warm Content purpose • Use case: product demo, brand spokesperson, educational content, virtual influencer post, sales video, onboarding clip • Platform destination: Instagram Reel, YouTube, LinkedIn, TikTok, website hero • Desired emotional response: trust, excitement, curiosity, aspiration Technical requirements • Clip duration: 2–4 sec / 6–10 sec / 15–30 sec • Aspect ratio: 9:16 vertical / 16:9 landscape / 1:1 square • Motion intensity: static with subtle animation / active gestures / high-energy movement Brand constraints • Color palette or forbidden colors • Brand keywords or phrases the avatar should embody visually • Any style references (films, games, other AI avatars) ---

The uncanny valley problem — and how to avoid it The uncanny valley is the psychological discomfort triggered when a synthetic human looks almost real but falls short in ways the brain cannot consciously articulate. Eyes that do not quite track. Skin that lacks micro-texture. Movement that is smooth but wrong. The brain pattern-matches to illness, deception, or death. There are two reliable exits from the uncanny valley: Exit 1: Go fully photorealistic. Push render quality, skin subsurface scattering, eye moisture, micro-expression, and hair fidelity past the threshold where the brain accepts the character as real. This requires explicit prompt language: "hyper-photorealistic skin texture," "subsurface light scattering on face," "wet corneal reflection," "micro-expressions," "natural breath movement." Exit 2: Commit to stylization. A clearly stylized character — 3D cartoon, cel-shaded, geometric — never triggers uncanny valley because the brain never expected biological realism. Own the artifice. Make it beautiful and internally consistent. The danger zone is the middle ground: a character that is clearly rendered but aspires to realism without achieving it. Avoid half-measures. Either push all the way to photorealism or lean fully into a defined non-realistic aesthetic. Additional uncanny valley avoidance rules: • Never describe eye movement without describing blink timing • Always specify natural weight and momentum in gestures • Avoid "perfect symmetry" — real faces are asymmetric • Include micro-imperfections: a strand of hair out of place, slight asymmetry in the smile • Ground the avatar with realistic environmental interaction: light falloff, shadow contact, hair affected by subtle air movement ---

The most persuasive style for commercial and B2B content. Optimized for spokesperson videos, testimonials, and brand ambassadors. Prompt markers: "photorealistic digital human," "hyper-realistic skin with visible pores," "subsurface scattering skin shader," "natural asymmetry in facial features," "wet corneal highlight," "professional studio grooming," "fine hair strands rendered individually" Best for: SaaS product demos, financial services, healthcare, e-commerce spokesperson Risks: Highest uncanny valley exposure — demand maximum fidelity or shift styles
